Introduction Categorisation is something that we do naturally and unconsciously every day. We recognise one animal as a cat and another as a dog. We organise objects in the world around us in ways that reflect these categories. In our kitchens, we keep baking trays with other baking trays, saucepans with other saucepans and keep food separate from cleaning products. We categorise ideas, people,...

The mainstream object categorisation community relies heavily on object representations consisting of local image features, due to their ease of recovery and their attractive invariance properties. Object categorisation is therefore formulated as finding, that is, ‘detecting’, a one-to-one correspondence between image and model features. This assumption breaks down for categories in which two e...

The automated categorisation (or classification) of texts into topical categories has a long his-tory, dating back at least to 1960. Until the late ’80s, the dominant approach to the probleminvolved knowledge-engineering automatic categorisers, i.e. manually building a set of rulesencoding expert knowledge on how to classify documents. In the ’90s, with the booming pro-duction a...

The subject of this article is project portfolio risk categorisation. Research conducted indicated categories containing the most probable and significant risks. research described in paper was carried out two stages. In first stage, relevant literature reviewed Delphi method used to identify 36 risks specific a portfolio. second respondents (project managers) assessed probability each occurrin...

In this paper we present a uniform approach to dynamic relationships in object oriented databases. We present our relationship categorisation based on dividing the object database into three virtual spaces each hosting entities of a particular type and show how relationships from the modelling domain map onto relationships in our categorisation. We present a relationship model and the semantics...

In this paper we present a taxonomy of dialogue moves which describe the actions that students and tutors perform in tutorial dialogue. We are motivated by the need for a categorisation of such actions in order to develop computational models for tutorial dialogue. As such, we build both on existing work on dialogue move categorisation for tutorial dialogue as well as dialogue taxonomies for ge...

Despite the importance of psychological essentialism as an account of categorisation, it is unclear what import findings of individual difference have. The present study is designed to investigate individual differences in relation to deference, a key indicator of essentialist thought. This replicates previous findings of individual differences in deference, and demonstrates a strong associatio...
